' loathe/tom it may com-( 1')! ,jBe it known that I; Ennnn'r Josue. acitizen of the l 'nited States, an(l a-resident o fQDanville, in .tbe'county of Pittsylvania and .State of Virginia. have made certain. new,and useful Improvements in. Spinning Machines, of which the following isaIspecification. i l

Y, My invention relates to improvements in spinning machines. and itconsists in the cQmbinations, constructions and arrange. ments hereindescribed and claimed. ;In ;the spinning of .yarns. the bobbinsnponwhiclrthe. yarn is wound have a primary winding which is termed thebunchf. This winding extends for a certain distance upwardlyfrom thebottom of the spindle and necessary for the purpose of providing anengaging" member for a feeler il IlCilLPIQVQHiZS the danger of windingoft of -all the,yarn on. the bobbin ina manner ivjell' known to the art.This so.-ca.lle,d fbunch'l. represents ust so much waste yarn orthreadand is a considerable source of loss since .with the large number ot'bobbins theiamount of yarn or thread which is consumed. making the bunchamounts to a very substantial item of expense.

provide a simple device of the type described whiclrmay be applied toexisting spinning machines without the necessity of dismantling themachines in any way or of machine. i

:Other objects and advantages will appear in the following specificationand the novel interfering in the ordinary operation of the features ofthe invention will be particularly pointed out in the appended claims.My inyention is illustrated in the accompanying drawings forming part ofthis application in which Figure 1 is a plan view of the device asapplied to a spinning machine. Fig. 2-is aside.view thereof. Fig 3 is anend view of the device showing 'its application to a spinning machine.Fig. "-l is ai face view showing, the relation of the cam and the maincam, Fig. is asectional' view along to Fig. 9. showing the a-uxili rycam in another position.

in explaining my invention it is necessary for me to describe and showcertain parts of a, .common typef spinning mechanism in order that theimprovement maybe readily understood. .1 will describe; however. only somuch of the old structure as isnecessary for a, thorough understani lingof my. improvement; 1 i

Referring especially to Figs. 3, and 7, I have shown therein a mainframe 1 *upon which is mounted astub shaft 2 bearing a builder aarinfito which is secured a sprocket chains which is attached at 5 to the armandzwhich passes around an idler 6 on a slidable plate carried by thearm, thenceover infe tom. bellrlrank levenl igwhichk isapivotedat 13 andwhose arm bearer-on a vertically slidable push rod 14 which is guided inbear- E'igs or slots 15 and which bears at its upper end a rail 16 whosereciprocal vertical movement is designed to guide the thread or yarnupon the bobbins such as that shown at 17 'in F 1;. Secured at the endof the power shaft 15 is a cam 19 which beans on a roller 20 on anadjustable plate 21 carried by the arm J.

As is well known in this art the winding oi the yarn upon the bobbin 1?is accomplished through the aid of the guide rail 16, beginning at thebottom of the bobbin and guiding the thread up and down 'for a raise.and lower. The progressive motion is caused by a ratchet wheel 22 at theendof a shaft '23 which is rotatably carried by the arm This shaft bearsa plate 38 which is loosely mounted thereon and which carries a pawl 23arranged to engage the ratchet wheel A fixed member A is disposed in thepath of the pawl so as to bring the latter into engagement with theteeth of the ratchet wheel-at each upward movement of the arm 3, thuscausing the rotation of the ratchet wheel at aoh upward movement. ()uthe'shat't 25 is disposed a worm it; which eugagcsa slidable rack member27 that bears an idler (i. It will be seen that as the ratchet is turnedthe worm 26 causes a movement of the plate 47 so as to slackcn-up thechain 4 and thus permit the pull rod 28 which operates the bell-crankhigher.

levers lever to move the push rod progressively The stroke of the pushrod 14, however. will be the same since it depends upon the shape andsize of the cam 19.

The parts thus described are old and form no partof my invention exceptin so far as they (:oiipcruto with the parts about to be described.

Referring particularly to Fig. 2 I have shown therein a bell-crank leverwhich is pivoted on a stub shaft 29 carried by a plate 30 secured to thearm 3 by bolts 31 or in any other suitable manner. ()ne arm 32 of thebell-crank lever bears a roller 33, the other arm 32" being connected bymeans of a link and turnbuckle connection 34. with a link 35 which ismounted on a pivot bolt 36 carried by the arm 3. The position of thebell crank 32", 32", and hence of the. cam roller :33, depends upon theposition of the stop member 36*. When the bell crank lever is in itseli'ective position. the stop 36 bears against the arm 32". The stop Mi-is carried by the plate Wand moves with it as the latter is moved bythe worm 26. On the power shaft 1 mount an auxiliary cam'37 which, aswill be seen, is smaller than the cam 19. This cam 37 is arranged tobear on the roller 33 when the hunch is being i made, the main cam 19also being in operation during the building of the bunch, but the deviceis so arranged that the main cam 19 alone comes into play for thefurther winding of the bobbin, as will be explained later. As statedbefore the shaft 25 bears a loosely mounted plate 38 which carries apawl 23 which engages the ratchet wheel 22. A second plate 38' whichbears a stop pin 39 is loosely mounted on the shaft 25 and is providedwith an extension 38 carrying a set screw 38 (see Fig. 1) which extendsthrough a slot 38 in an enlarged weighted portion 38 of the plate 38'.This construction forms a means by which the. relative position of thepin 39 with respect to the pivotal support of the pawl 23 may be varied.This pin 39 extends underneath the pivotal support 36 of the link Fromthe foregoing description of the various parts of the device theoperation thereof may be readily understood. The purpose of theauxiliary cam 37 is to shorten the stroke of the large cam 19 while thebunch is being made. The cams are placed in the relative positions shownin Fig. 4 so that during the rotation of the shaft 18 which bears thecams,the auxiliary cam 37 will at times engage the cam roller 33 so asto move the arm 3 from the control of the cam 19 and thus cut thestrokein two or shorten the stroke while the hunch is being made, as will beexplained later. The normal position of the roller 33 at the beginningof the winding operation is that shown in dotted lines in Fig. 2, orthat shown in detail in Fig. The roller 33 is held in this position bythe engagement of the arm 32" of the bell crank lever with the stop pin36 which, as stated before. is carried by the plate 27 and which atthebeginning of the operation is in the position shown in Fig. 9. Itwill be understood that the arm 32 gradually recedes, as explainedlateryfrom the position shown in Fi g. 9. which finally allows the higharts of the cam 19 to come into contact wit 1 the coacting roller 20 andactuate the builder arm jointly with the action of the cam 37 on theroller 33. The rotation of the auxiliary cam 37 will cause thereciprocatory rocking of the arm and this will cause the guide rail tomove up and down so as to wind the bunch onto the bobbin. During theupward movement of the arm 3 the pawl 23 will strike the fixed member 24and will thus cause the turning of the ratchet wheel. As

the ratchet is turned the shaft 25. which is secured to it will berotated and the movement of the screw 26 will cause a movement of theplate 2'? so as to move the stop pin-36 from the. position shown in Fig.9 toward that shown in Fig. 10. This will permitthe lower end of thelink bell crank lever to move from the position shown in Fig. 9 towardthat shown in Fig. 10. It will be understood that this move ment isvery:slight for each up and down movement of the arm. On the upwardmovement of the arm, the plates 38 and 3S,

the pawl 23 which is carried by the former, and the pin 39 which iscarried by the lat ter, will resume their original positions because ofthe fact that the end 38 of the plate 38 together witlithe extension ofthe plate 38, overbalance the pawl and pin' end of these plates, therebycausing them to ascend until the pin 39 strikes the arm 3. In the nextforward movement, the pawl'23 will the link 35 which is connectcd'to thebell crank lever by the turn bucklecoiinection is gradually assuming averticalposition d'uring the progressive movement ot'tlie pin36. Thelink 35 finally gets the path of the pin 89 so that the'latter on itsreturn by the weighted end of the plate does not reach its normalposition, but is now stopped'by the This prevents thepawl 23 from ridingover as many teeth as it would at the beginning of the operation, andhenceshortens the angle through which the 'atchet wheel is rotated. Theauxiliary cam 37 is now out of commission because the cam roller 33 hasbeen lowered'past the point of engagement with the cam 37. This allowsthe large cam 19 to have full control of the stroke of the arm 3.

the arm 3 will now be a maximum, thatis to say, thestroke will'no'wconform to the requirement for winc'ling the thread on the bobbin, thebunch'having been made. While the cams 19 and 37' are working conjointlyto cause the reciprocation of the arm during the making-of the bunch, ashort stroke is produced, but when the cam 19 takes full control a long,stroke is produced. Now it is essential that the rotation of the shaft25 which is caused as stated by the engagement of the pawl :23 with thefixed member 24-, shall be substantially the same during each strokewhether the stroke be short or long for the reason that the building ofthe thread on the bobbin must be uniform. It will therefore be seen thatwhen the link35 comes into engagement with the pin 39 it will stop thereturn movement of the pawl at such a point that subsequent .long'strokes will move the pawl substantially throughthe same are as it ismovedby the short stroke when the link 35 is out'of the way of the pinso as to permit it to have areturn movement until the pin engages thearm This feature I regard as one of the most important features of myinvention, be,
